Back in the day

Neptune is notable for being the first planet to be discovered by way of mathematical prediction rather than standard observation. Galileo observed Neptune twice in the early 1600s, but he mistook the planet for a fixed star and therefore is not credited with its discovery. Centuries later, small changes in Uranus's orbit led astronomers to seek out and discover the eighth and outermost planet of our solar system. Who predicted Neptune's location in the 1840s within 1Â° of where it was found?

Augustus Caesar was the first emperor of Rome. Known as Octavian for the period of his life prior to 27 BCE, he came to power after defeating Mark Antony and Cleopatra. He ended a century of civil wars and gave Rome an era of peace, prosperity, and imperial greatness. Although he preserved the outward form of the Roman Republic, he ruled with extraordinary powers for more than 40 years and filled the Senate with sympathizers who named him "Augustus."
